I can get the code to execute the proper message - but get BUMMER message

var money = 9; var today = 'Friday';

if ( money >= 100 || today !== 'Friday' ) { alert("Time to go to the theater");
} else if ( money >= 50 || today !== 'Friday' ) { alert("Time for a movie and dinner");
} else if ( money > 10 || today !== 'Friday' ) { alert("Time for a movie");
} else if ( today === 'Friday' || money < 10) { alert("It's Friday, but I don't have enough money to go out");
} else { alert("This isn't Friday. I need to stay home."); }

script.js 
var money = 9;
var today = 'Friday';

if ( money >= 100 || today !== 'Friday' ) {
  alert("Time to go to the theater");    
} else if ( money >= 50 || today !== 'Friday' ) {
  alert("Time for a movie and dinner");    
} else if ( money > 10 || today !== 'Friday' ) {
  alert("Time for a movie");   
} else if ( today === 'Friday' || money < 10) {
  alert("It's Friday, but I don't have enough money to go out");   
} else {
  alert("This isn't Friday. I need to stay home.");
}

if ( money >= 100 || today === 'Friday' ) { alert("Time to go to the theater");

This first condition tells us that money (9) is greater than or equal to 100, Which is FALSE.

The second condition tells us that today is strictly equal to friday, which is TRUE.

This is followed by an || which is a sign that if just one condition is TRUE, then the whole statement is considered to be TRUE and you will ignore all the upcoming IF's and ELSE IF's.

However, that is not the case because the first statement is FALSE.

With the && operator, the whole statement will be considered to be FALSE, because ONE condition is FALSE. Because of this, it proceed to the next ELSE IF's to test the next conditions.

Hope this explanation helps. :)
